DUMPLCAR.

Specieation of Letters Patent.

Patented Sept. 24, 1907.

Application filed December 12,1906. Serial No. 347,473.

To all whom it may concern:

Be it known that I, WILLIAM Q. OLDEN, a citizen of the United States, residing at Chicago, in the county of l accompanying drawings.

This invention relates to dump-cars of that class in which the material is discharged through a large central opening which is normally kept closed by suitable swinging doors. I

The obj ect of the invention is to provide an improved door construction and improved means for operating such doors. I accomplish these objects by the construction shown in the drawings and hereinafter specifically described.

That which I .believe to be new will be pointed out in the `cl ims,

In the drawings,-Figure 1 is a longitudinal section Athrough a portion of a car, in which my improvements are embodied,l such section being taken at line 1-1 of Fig. 3; Fig. 2 is a horizontal section taken at line 2-2 of Fig. 3,' Fig. 3 is a vertical section taken at line 3-3 of Fig. 2, showing the doors in their closed position; Fig. 4 isa view similar to Fig. 3 but taken at line 4--4 of Fig. 2; Fig. 5 isY a view similar to Fig. 3 but showing the doors opened to permit the discharge oi material from the car; and Fig. 6 is an enlarged detail, being a perspective view of that member or part 4of the togglelever mechanism that carries the counter-weight.

In the drawings I have shown a construction of carbodyA which forms the subject-matter of my pending application, Serial No. 344,080, filed November 19, 1906.k I shall, therefore, describe such car construction briefly and only so far as is necessary to an understanding of my present invention.

10 indicates the side sills of the car, which, as shown, are formed oi channelirons, and l1 are the sides, preferably formed. of girdcr construction.

12 indicates plates extending longitudinally of the car at each side of the car.

13 indicates inclined Hoor plates at theends of the car, and 14 inclined floor plates at the sides of the car. The lower ends of these several incl-ined floor plates are turned down into substantially vertical position, as clearly shown in Figs. 3,'4 and 5, and form theside walls of a large central opening l5 through which the material from the car is discharged.

16v indicates a bolster extending transversely of the car near one end. A like bolster, of course, is to be provided at the other end ofthe car.

17 indicates center sills, two of such sills being provided at each end of the car. The sills at each end arspaced apart so that provision is made between them for the usual draft-rigging. Each pair of center sills .extends inwardfrom the end of the car and terminates y near the inner end of the long central opening 15, beore referred to. 18 indicates a plate extending transversely of the car next to the inner face of the bolster I6 and lying upon and secured to the said centen,

sills 17.

The various parts of the framework of the car are suitably riveted together-.al1 as more specifically set forth in my said pending application.

19 indicates four channel-irons, two at each side of the central opening l5, each channel-iron extending from one of the side sills 10 inward and terminating at its inner end near one of the side walls of such central opening. Each channel-iron- 19 isto be secured in place by suitable rivets and brackets to its adjacent side sill l0 and by rivets to one of the longitudinally.- eXtending plates 12. In the construction shown, these hchannel-irons are shownas each located so as to be about midway between one end of said central opening and its longitudinal center, as best shown in Fig. l. 20 indicates plates, one of such plates being securely riveted to the face of each of the channel-iron supports 19 and projecting below such channel-iron support, as clearly shown in Figs. 3, 4 and 5, These channel-irons and plates that are secured thereto form the supports for the doors thatclose the large central opening l5 and also for the toggle levers used in operating. such doors and hereinafter described. riwo doors are employed for closing said central opening, each door, in the con- Y tially vertical, when the doors are closed, whereby the inner faces of such turned ends will abut, as clearly shown in Figs. '3 and e, and thus insure a tight joint. To the under face of each door 2l are securely riveted a number' of Z-shaped angle-irons, against the lower face of which are suitably secure-'lV two beams 25, preferably of angular shape. Each door beam is pivoted `at' 2G to one of the supports formed by a channel-iron 19 and -plate 20.

v 27 indicates an arm pivotally attached at its lower end by a pivot 28 to the lower end of one of the beams 25. 29 indicates two other arms, shorter than the arms 27, each of said arms 29 being pivotally attached at its outer end to one of the depending plates 20 that is carried by I shown in Fig. 5.

one of the channel-irons 19. Each arm 29 is provided, as clearly shown in Fig. 6, with a hub vor boss on its outer "ace, which hubs or bosses come against theinner faces of the depending plates 20 and thereby hold the arms 29 suiiiciently away from the plates 2O to permit the arms 27 that are connected with the arms 29 to move freely past such plates 20, when the doors are open, as The arms 29 are pivotally attached to their respective plates 20 by pins 31 passing through their hub portions 30 and said plates.

32 indicates the pins that pivotally unite the arms 27 and 29 together, the openings through the arms 29 lfor such pivot pins' being located a little distance from the inner' ends of such arms 29, as clearly shown in Fig. 6. Each pair of arms 27 and 29 constitutes a pair of toggle levers. The long arms 27 of the double toggle that is thus formed for operating each door are formed separate from each other, but the shorter arms 29 are connected together, and the connecting means employed is a very heavy bar 33, which, in the constructionv shown, is oi angular form, and the function of which is to act as a counter-weight to close, or assist in closing, the doors after the load has been discharged from thecar.

34 indicates ears formed on the face of the angular counter-weight 33, between whichis pivotally secured by a pin 35 the lower end of a rod 36 that extends upward through a suitable opening 37 in one ofthe plates l2 and is pivotally connected by a pin 38 to one end of a bell-crank lever 39 that is pivoted at 40 between a pair of supports 4l tht are suitably connected to the upper face of the longitudinally-extending plate 12-these supports 4.1 being, in the construction shown, formed of angle-irons. y

42 indicates a connecting bar, which, for purposes of strength, is made of inverted 'JJ-shape. This bar is pivotally connected at 43 with one arm of the bell-crank lever 39 and at its other end is connected at 44 with one end of a cross-head 45.

There are4 two sets of operating devices, one set for each door, and each is constructed in themanner already described. The two connecting rods and the parts to which they are respectively connected are best shown in Fig. 2.

. 46 indicates suitable guiding supports extending between one of the bolsters 16 and the end oi the car upon which the cross-head 45 rests.

47 indicates an air-cylinder, in which is located a piston, as usual, to which piston is connected a piston-rod 48, the outer end of which is secured to the central portion of' the cross-head 45. This cylinder, in the construction shown, is suitably secured in an open framework 49 that is supported between the adjacent bodybolster 16 and the end ofthe car.

50 indicates a pipe, through which air under pressure is supplied to the cylinder. suitable source of supply, which may be either a train pipe leading from the engine to which the' car is attached or the auxiliary reservoir of the ordinary brake system.

I have called attention to the fact thatfthe doors, when in their closed position, as shown in Figs. 3 and 4, are sharply inclined. This arrangement of the doors increases quite considerably the capacity of the car, but

it is, of course, necessary that there be a protecting de-y vice at the ends oi the doors to prevent the escape oima- This pipe connects with a i terial at those points. I therefore provide opposite each' end of the doors a plate 51 of triangular shape, which is secured against the ends of the center sills 17,-short angle-bars 52 (see Fig. 4) being employed to effect this connection,-and said plates are further secured by riveting their upper edges to the downwardly-turned edges of the inclined floor sections 13 that form the end Walls of the large central opening 15. The inclinedy edges of these triangular plates are turned inward to form flanges which act not only to stiften the plate but serve as surfaces against which the face plates of the doors abut, thereby forming a tight joint. These anged edges of the triangular plates are indicated by 53.

With the doors in. their closed position, as shown in Figs. 3 and 4, and with the carl loaded with material which it is desired to discharge through the opening 15, air will be admitted .tothe cylinder 47 and, ot' course, move the piston thereinand through the piston-rod 48 force the cross-head Adfinward or toward the centerof the car. Such movement of the crosshead, ofcourse, is transmitted .through the connecting bars 42 to the bell-crank levers 39, 'causingy such bellcrank levers to turn upon their pivots 40 with the result of drawing up the 'rods 36 which'are pivotally attachcd, as before described, toyjthe bell-crank levers. The upward strain oi these rods 36 on the short arms 29 of the toggle memberscauses the ends of the toggle arms that are pivoted together to turn on their pivots 32, and as such pivotal points 32 are raised out of.` line with the pivotal points 28 and 31 the two doors will, of

will continue swinging open until stopped 'ina substantially vertical position, 'as indicated in Fig. 5. The

The con? stopping of the doors in this position is secured bythe i longer face oi the counter-weight 33 being Ibrought to rest against the under face of its adjacent longitudinal plate 12. Upon the closing of the doors the bell-crank levers will be brought in contact with the plates 12, thus providing a positive stop for the downward movement of the toggle-levers. As is best shown in Fig. 5, when the doors are opened the inclined upper ends 22 of the wearing plates of the doors will project in under the side edges oi the large discharge opening so as to properly deect any material that might otherwise have a tendeny to pass to one side or that would accumulate on the door if the inner ends of the doors were square. Furthermore, it will. be noticed by reference to said Fig/5 that owing to this inclination of that end of the wearing plate of the door and also owing-to the pivot pins 26 being set back or to one side of the edge of the discharge opening, a considerable space is left between the upper edge of the door and the adjacent side of the discharge opening, through which a rod or other tool 4can be inserted in case any obstructions form there that need dislodging.

From the foregoing, it will be evident that 'm practhat is, after the members 27A and 29 have their pivot pins 32 raised out oiline with the other pivot pins 28 and 3l-the weight of the load will generally' be suflicient to overcome the Weight imposed by the counterweight device. 33 sothat the parts will be quickly v scribed.

moved intoA the positionshown in Fig. 5. The, air pressure, however, is to be kept on during the unloading operation,in order that the doors may not be prematurely closed. For it is to be understood that the counter-weight device 33, extending as it does far beyond the pivots 32, exerts pressure enough, when the devices are not supported by air pressure from the cylinder, to force the toggle levers down and as a result of such forcing down cause the doors to close. From this it is evident that under normal conditions all that is necessary to be done to closethe doors is to destroy the air pressure in the cylinder in the usual manner, and immediately upon its occurring the colinter-weight7 serves to close the doors instantly,as deln order that the doors maybe opened or closed when through any cause the air pressure device is inoperative, I -provide hand-operated means for moving the bars 42 toward the center of the car to cause an opening ofthe doors, or in the reverse direction tocause a closingbf the doors. These hand-operated means are provided at 'the same end of the car as the air cylinder 47 and consist of two horizontal shafts 54, which, in the construction shown, are in line with each other, and each of which is provided on its inner end with a handwheel 55. Each shaft is provided with two chains, onev of which, 56, is fast at one end to said shaft and passes over a pulley 57 suitably journaled in brackets attachedl to the bolster 16 and the other end of said chain is attached to one end of the cross-head 45. The other chain referred-to is indicated by 58 and is also made fast at one end to the shaft, and after passing over a pulley 59 that is suitably secured near the end of the car,

is attached at its other end to said cross-head 45 a short distance from the 'end of the cross-head. Two of these handdevices are provided, as stated. One'of them is` indicated in full lines in Fig. 2, while the other is represented by broken lines, except that at the side` where the device -is indicated yin broken lines portions of the two chains 56 and 58 are shown infull lines. It is evident that when these shafts 54 are turned in one direction one set of chains will be wound around the shafts and.. exert a pull on vthe cross-head that will move it toward the end of the car, while the other set of chains will unwind from the shafts, but when the shafts are turnedinlthe reverse direction the set of chains that had before exerted the pull on the cross-head will unv wind fromthe shafts, while the other lset of chains Will wind up thereon and exert a pull on the cross-head in 'the other direction. By these means the' doors can be openedor closed by hand. Any suitable ratchet device may be employed in connection with the hand- Wheels and shafts for holding them against rotation when the doors have been fully opened so that the doorsv may not be prematurely shut by reason of the force exerted on the toggle devices by the counter-weight.

-By myimprovedtconstructionI provide doors that `two pairs of toggle-levers, one member can be opened with but slight effort, and when opened will remain' in a xed position so as to act to properlyJ direct the material being discharged, and which arel capable of automatically closing by reason of the construction and arrangement'of the counter-weight appai ratus attached to and carried by the toggle-levers pivotally attachedlto the doors. Furthermore, by reason of the location of the door-operating bars and bellcrank levers connected therewith beneath the inclined iioor sections at the sides of thecar, such parts are protected and are also easy of 4access for any purpose. The arrangement of/the cylinder and the cross-head connected thereto, as well as the auxiliary hand-operating devices, beneath the inclined floor section at one end of the car also provides for these parts being protected as well as making them readily accessible.
